This permanent magnet pot assembly is made by sticking a permanent magnet (using new materials and standard grade) into a steel cup that with the external thread or male thread. Steel nut and screw cap can be fixed on the external thread. We usually glue neodymium disc magnets into the steel cups. The steel cups can not only protect the disc NdFeB magnet but also ensure the NdFeB disc magnets strongest magnetic force and holding ability. The steel cup of the pot magnets with eyelet can be made by lathing or punching. We have both two kinds of pot magnets with closed hook for sale.
Countersunk pot magnet is just flat round base pot magnet with the countersunk hole in the center. We usually make the countersunk pot magnets by fix 90 deg countersunk ring NdFeB magnets into flat round steel cups, there is the same size hole in the center of the steel cup. The countersunk hole is suited for the screw to fix the countersunk pot magnets onto other objects.
Countersunk cups are neodymium magnets housed in a stainless-steel cup with a countersunk hole that goes thru the entire assembly. The countersunk feature allows the magnet to be mounted to any surface with a standard 90 deg flat head screw.
Following are some applications of pot magnet with countersunk for your reference, more applications is waiting to be discovered by you:

Remark: the strength is the vertical magnetic pull-force which make the magnet pull away from the 1.18'' thickness steel plate of a tester under ideal condition, it does not mean the actual weight which the magnet can lift the actual pull force will vary mainly depending on the following variables:
A: Steel thickness (the thicker the steel is, the stronger the pull force)
B: Attracting position (the farther beyond the center of gravity of the attracted object, the lower the pull force)
C: Pulling direction ( the smaller the angle taking 90°as a standard, the stronger the pull force), the pull force in horizontal direction is only about one third of that in vertical direction)
Following is our standard sizes of pot magnet with countersunk hole for your choice, if there is no size you need or some different requirement, please contact us to custom:
Package of pot magnet with countersunk hole:
Shipment: Magnet can be shipped by Air, Express, Truck and by sea. But it must be shielded if by air or Express.
How to promise the quality: Quality is our culture! To ensure our quality, all magnets are produced with 100% new standard material rather than recycle or bad material. Besides our professional QC department will inspect the magnet for each stage, including magnet grade, coating, dimension, tolerance and pulling force for pot magnet, magnetic hook, fishing magnet or other magnetic assemblies. So that our magnet pass rate is as high as 99.5%.
Testing reports of magnet
Sample:Sample of pot magnet is available to provide within 2 days if we have it in stock. Otherwise, it takes 7days to customize.
MOQ: Usually we don't require special MOQ of regular magnet or pot magnet for you, small order is available to accept. If you ask for special custom magnet or pot magnet and it needs mold to produce, MOQ is decided as product details.
Custom service: Custom service is our advantage. Multimagnets has a professional technical team to support our customers. We can provide professional CAD drawing, strength simulation of magnet / pot magnet, even that Multimagnets can assist you to design a new magnet. For some Amazon customer, Multimagnets always provide free labeling and professional photos taking.
